The only thing i have seen that is even close to a problem, is the lack of maintenance of the air filter. I am a honda service mgr at a store in Nebraska. Lots of farmers and ranchers using these,mostly 1000's. the ONLY issue is the consumer not doing more then reg sched maint on the air filter. very dusty conditions can fill that filter up in a day. honda has pointed out, if you have a cabin on the 500's or 700's, CHECK AIR FILTER DAILY!!!!!! Get a spare,I tell them,then it is only 1/2 of the drag to change it more often. keep one filter maintained and in a big ziplock baggie, and its' not a big deal to change it often. pretty cheap insurance for the engine. I tell my cust all the time, "clean air. clean oil & that's all they need for a long happy life". Some have not listened,sad.
